I didn't say how many deuces, and they're easy to find - go into a bank, especially if you are a customer at that bank, and let them (if you are a customer) you'd like to make a withdrawal in $2s, they will usually tell you they don't normally get them, but that they will in their next cash order, and in about a week you come back, make the withdrawal in a strap of 100 $2.

No problem for me at Bank of America, but now that I am no longer a customer, I will carefully try again, as a cash exchange with them.
